X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

UK to Push Hydroelectric Expansion

LCG, July 20, 2001Brian Wilson, the new energy minister in Britain's Labour government, was expected to announce plans today for an expansion of hydroelectric power as a means for the UK to meet climate change targets.

The proposals are expected to set in motion a 250 million ($350 million U.S.) hydroelectric program by Scottish and Southern Plc, the Financial Times said. Scottish and Southern is the UK's largest hydroelectric generator.

Wilson's plan is to extend the government's renewables program to include all new hydroelectric facilities and recondition plants of up to 20 megawatts, instead of the earlier limit of 10 megawatts. The proposal would likely draw fire from environmentalists who claim larger facilities damage eco-systems and endanger wildlife.

Earlier this week, Wilson said that if the UK is to increase its reliance on renewables from the present 3 percent to the target of 10 percent of British generation "there has to be some give and take from environmentalists."

Wilson added, "The government is expected to create a 1 billion market for renewable energy by 2010. The main driver for this will be the renewables obligation so it is crucial that this mechanism encompasses hydroelectric power."

Scottish and Southern owns 56 hydroelectric plants in Scotland with a combined capacity of about 1,000 megawatts.
